Pelagic Zone

Pelagic Zone

Pelagic Zone This zone is characterized by open water and is located far from the shore. It is inhabited by a large number of fish, as well as microorganisms that support the complex biological network in the lake. Characteristics of the Pelagic Zone: Fish: This zone contains several fish species, such as the Ohrid trout (Salmo letnica), which is endemic to the lake, as well as other fish species like Alburnus and Gobio. Fauna: The pelagic zone also houses microorganisms such as bacteria and plankton, which are a primary food source in the lake's food web. Temperature and Chemistry: This zone has constant temperature and chemical composition in the deeper areas. Lake Ohrid is oligotrophic (low in oxygen), meaning that less oxygen exists in the deeper layers.
